FOUNTAIN-BRUSH.

To all whom it may concern:

Be it known that I, OTTO A. Mrn'rznnn, a subject of the Emperor of Germany, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Fountain- Brushes, of which the following is a specification.

The present invention relates to improvements in fountain marking devices for supplying ink or other marking liquids to a brush or other marking device.

The object of the invention is to provide such a device which, while preventing leakage of the marking liquid, will be simple and cheap in construction, and by which the ink or other marking liquid can be supplied to the marking device at any desired rate of speed.

I have herein shown the invention as applied to a brush, but it is to be understood that, with suitable changes which will readily suggest themselves, it can also be used with a pen or other marking device.

In the accompanying drawing, Figure 1 is a side view of a fountain brush con structed in accordance with my invention, and Fig. 2 is a vertical section thereof.

Referring to the drawing, 1 indicates the bristles of the brush, the inner ends of which surround a short tube 2 of wood or other suitable material, and are compressed within a thin sheet metal cylinder 3. Extending through the tube 2 is a metallic tube 4 connected at its upper end with a coaxial ink chamber 5, and which has a base 6 wider than the tube 4, a conical or upwardly tapering wall 7, and a narrow top 8. To prevent the tube 4 from turning, there is secured thereto the inner end of a narrow plate 9, the outer end of which is bent downward, as shown at 10, its lower end having a slot 11 opening in the bottom, and engaging a in 12 extending inwardly from the cylinder 3. The tube l can thus be drawn out of the tube 2 upwardly, and when replaced therein is prevented from turning by the engagement of the pin 12 with the slot 11. Partly supporting the tube l and surrounding it is a coiled spring 13 the lower portion of which is received within an enlargement i l of the bore of the tube 2 and which is compressed between the plate 9 at its upper end and, at its lower end, a leather washer 16 surrounding the tube a and seated in the bottom of said enlargement.

Serial No. 786,431.

Fitting around the conical wall 7 of the chamber 5 is a conical wall 1'? of a cavity 18 formed in the bottom of an ink reservoir 19 having a reduced threaded open upper end 21 through which the reservoir can be filled with ink or other marking liquid, a cap 22 being screwed on said end, and having a hook 23, by which the device is suspended. A washer 2a of cork or other suitable material, is pressed between the cap 22 and the upper end of the reduced portion 21 to make it liquid tight.

In order to hold the conical wall of the cavity of the ink reservoir in close proximity to the conical wall of the ink chamber, while at the same time permitting for reasons which will be hereinafter disclosed, its rotary movement relative to the ink chamber, the lower portion of the ink reservoir is enlarged to form an annular shoulder 26, and, surrounding the lower portion of the ink reservoir and the upper portion of the cylinder 3, is a sleeve 27 formed with an annular shoulder 29 conforming in shape to the annular shoulder 26. The lower portion of the sleev 27 its tightly around the cylinder 3, but the upper portion is spaced from the ink reservoir 19 a short distance to permit the passage of said sleeve over a pin 31 em tending outwardly from the ink reservoir, the upper edge, however, of said sleeve being bent to closely surround the sleeve except a small cut-away portion 32 of said edge. The lower edge of the sleeve is formed with a bayonet slot 253 which engages a pin 3d secured on the cylinder 3 and extending outwardly therefrom.

In order to permit the ink or other marking liquid to flow from the ink reservoir to the ink chamber, the conical walls 17 and 7 are formed respectively with small apertures 35 and 37, which, when caused to register by the rotary movement of the ink reservoir, permit the ink to flow from the reservoir to the chamber, and when out of registry do not permit the flow.

In order to admit air in regulated quantity into the ink reservoir to replace the ink which has flowed therefrom there is secured to the top of the chamber 5 the lower end of a stout wire 41, which extends through the top of the cavity 18 and then upwardly in said reservoir but in an oblique direction, terminating at a point closely adjacent to an air hole d2 in the contracted portion of the reservoir, immediately below the edge of the cap 22. On the upper end of the rod all is secured a valve 4:3, which when in the proper position, can close said hole 42. The hole 42 is so located in the wall of the ink reservoir that it is closed by said valve when the apertures 35 and 37 are closed, and open when said apertures are in registry with one another, so that, whenever the ink reservoir is turned to permit the ink to flow to the ink chamber, air is also permitted to flow through the air hole 42 into the ink reservoir.

By the above construction I provide a fountain marking implement in which the flow of the marking liquid can be regulated as desired, or entirely arrested, and which will not leak. Many marking liquids are composed in a great measure of oil, which will leak through a very minute passage. Hence it has been diiiicult to provide such a fountain marking device which will not leak. The present construction overcomes these difliculties. F or the arrangement of the conical wall of the chamber within the conical wall of the cavity of the ink reservoir, and the spring for pressing said walls together, prevent the leakage of the marking liquid between said walls; and the provision of the leather washer around the tube and in the bottom of the enlargement of the tube 2 and of the spring for pressing said washer against said bottom, prevent the leakage of the marking liquid between the tube a and the tube 2.

1. In combination with a marking device, a liquid chamber having a conical wall, a tube leading from said liquid chamber and communicating with the marking device, a liquid reservoir having a conical wall fitting closely against the first-named wall, said walls having openings arranged to register with each other, and means for pressing one of said walls tight against the other.

2. In combination with a marking device, a tube communicating therewith having an enlarged inner portion, a liquid chamber having a conical wall, a tube leading from said liquid chamber into the firstnamed tube, a liquid reservoir having a conical wall fitting closely against the firstnamed wall, said walls having openings arranged to register with each other, and a spring coiled around said latter tube and one end of which is received within said enlarged portion of the first-named tube, for pressing said former wall against the latter.

3. In combination with a marking device, a tube communicating therewith having an enlarged inner portion, a gasket in said enlarged portion, a liquid chamber having a conical wall, a tube leading from said liquid chamber into the first-named tube, a liquid reservoir having a conical wall fitting closely against the first-named wall,

said walls having openings arranged to register with each other, and a spring coiled around said latter tube and one end of which is received within said enlar ed portion of the first-named tube, for pressing said former wall against the latter and pressing against said gasket to close the space between the tubes.

l. In combination with a marking device, a liquid chamber communicating therewith, and a liquid reservoir coaxial with, and rotatable relatively to, said chamber, said reservoir and chamber having conical walls, the conical wall of. the reservoir fitting closely around that of the chamber, said walls having openings adapted to register with each other, and a spring for pressing the conical wall of the chamber against the corresponding wall of the reservoir.

5. In combination with a marking device, a tube communicating with the marking device, a liquid chamber, a tube communicating therewith and passing into the first-named tube, a gasket closing the space between the tubes, and a spring pressing against said gasket.

6. In combination with a marking clevice, a liquid chamber communicating therewith, and a liquid reservoir coaxial with, and rotatable relatively to, the liquid chamber, said reservoir and chamber having respectively concave and convex walls fitting against each other with registering openings, a sleeve surrounding said reservoir and chamber and having a part engaging the reservoir, and means for pressing said sleeve and chamber in opposite directions to press said walls together.

7. In combination with a marking device, a liquid chamber communicating with the marking device, a liquid reservoir coaxial with, and rotatable relatively to, the liquid chamber, said reservoir and chamber having respectively concave and convex walls fitting against each other with registering openings, said reservoir having an annular shoulder, a sleeve surrounding said chamber and reservoir and having an annular shoulder abutting against the firstnamed shoulder, and a spring pressing said sleeve and chamber in opposite directions.

8. In combination with a marking device, a tube within the marking device, a liquid chamber, a tube communicating therewith and passing into the first-named tube, a gasket closing'the space between the tubes, a liquid reservoir coaxial with, and rotatable relatively to, the liquid chamber, said reservoir and chamber having respec tively concave and convex walls fitting against each other with registering openings, said reservoir having an annular shoulder, a sleeve surrounding said chamber and reservoir and having an annular other, said reservoir having an air opening, and means immovably secured to the liquid chamber for closing said opening.

In testimony whereof I have hereunto set 15 my hand in the presence of two subscribing witnesses.
